"Barcelona and Villarreal CF have agreed to terms for the player Jonathan dos Santos," the statement said. "The transfer fee, which is a combination of a fixed sum and variables, could reach two million euros, and FC Barcelona reserve the right to be involved in the possible future sale of the player."

Dos Santos is unlikely to be the last squad player to leave Barca this summer, with new coach Luis Enrique and sporting director Andoni Zubizarreta reportedly hoping to move on Cristian Tello, Isaac Cuenca, Bojan Krkic, Oier Olazabal, Ibrahim Afellay and Alex Song.
